本文介绍了一种新型的全髋关节置换术中骨盆前平面位姿和假体植入角度的实时测量系统。该系统包括三个部分：初始位姿测量仪（IPMI），用于确定骨盆前平面（APP）的初始位姿;实时位姿测量仪（RPMI），用于获取APP的实时位姿;髋臼杯角度测量仪（AAMI）。实验结果表明，APP位姿均方根误差小于1.6 °，髋臼杯植入角度小于3 °，满足全髋关节置换术的要求。
We demonstrate a novel real-time measurement system for pose of anterior pelvic plane and implantation angles of prosthesis in total hip replacement (THR) surgeries. The system includes three parts: initial pose measurement instrument (IPMI), which is used to determine the initial pose of the anterior pelvic plane (APP), real-time pose measurement instrument (RPMI), which aims to acquire the real-time pose of the APP, and acetabular cup angle measurement instrument (AAMI). The experiment results show that the root mean square error of pose of APP is less than 1.6 degrees, and the implantation angles of acetabular cup is less than 3 degrees, which meets the requirement of THR surgeries.
